Katie Lee looked majorly cute at a book party soiree for Derek Blasberg's Classy at Barneys in NYC. She took a cue from the floral minis trend and donned a watercolor version from J.Crew with a white double-breasted blazer. A white tank keeps her palette simple, while lace booties add textural pizazz. We love it all.
